Pogoplug v2 MAC address is not found

[vfilipch]

Hello everyone!
It is my first attempt to install Arch.
My device is Pogoplug v2 (pink/gray) with 1Tb hard drive connected via USB.
I followed instructions at https://archlinuxarm.org/platforms/armv ... 2-pinkgray.
It seems everything was ok. Last message after step 8 was:

$this->bbcode_second_pass_code('', '/tmp # sh pogo_e02.sh

But after reboot I don't see the device's MAC address on my network. I don't see any new MAC either.
So I cannot use ssh to login.

If anyone had this problem before, please advise what should be my next steps in resolving
